Hero: Has been card dead and has not had any post-flop play for almost an hour.

Villain: Tight but very aggressive. Have seen 3 played hands. The first two included big PSB from late position on a two-tone flop and then he angrily folded when the flush hit on the turn. The third was a 7xBB bet behind two limpers where both folded.

Questions:
1. Should I have 3bet pre-flop? I thought about it and decided not to since ATs is more of a drawing hand and the chance of iso-raising with 3 players willing to call a 6xBB from the MP was slim in my eyes.

But if I had raised I probably would have gotten Villain's 44 to fold...

2. Should I have let the flop check through? I figured I had a decent chance to win the pot right there. And even if I didn't I knew I had loads of equity (around 44%). I was planning to shove a blank turn or check another club to induce a bluff.

Most of the questions that you asked are personal preference. I do not think a 3 bet is good here because you are going to have to make it pretty large to fold out anyone. I do not mind your flop play making the assumption that you do check this back some of the time. You had a big draw, got it in, and you lost. I wouldn't think about it too much. Move on to the next hand.

I think I would just call preflop. I guess it would be a good squeeze spot, but I'm not sure how often you are going to take it down and you do have a good amount of equity.

I like a bet postflop. You hit a pretty big draw and you are not going to need to win the hand unimproved a lot to make it profitable. Betting gets out the smaller pocket pairs. Unfortunately you ran into a set. Sucks, but it happens. You played the hand fine.

I'm not really concerned about the results of the hand since I think I just got really unlucky. I'm more curious about the two questions I asked because I find myself in similar situations where I am not sure about what to do.

When I have a good hand pre, I have the strongest urge to iso-raise, but I always convince myself that nobody will be folding so there is no point. I also find myself wondering if I should be playing big draws strongly or just passively waiting for them to hit because calling stations will probably pay me off regardless.

Played perfectly IMO. Only thing that might be different is preflop...how tight MP raising range is, or how tight the other callers are might make ATs a fold. Reraising pf is pretty terrible under most circumstances IMO.

I think that you have to be in a situation where there are not so many people in the pot to make a 3bet with ATs. If you have a really strong hand, just go nuts with it.

As far a flop action with big draws, I think that you should just mix it up. There are not too many mistakes to be made with big draws.

That's very interesting. What kind of situation is folding ATs a good idea? Even if I knew for a fact that MP only raises with JJ+ I think I still would have called as long as he had a caller or two behind him.

I think 5 ways and being last to act I am semibluffing only my combo draws. AcXc I check back and hope to hit. The extra 3 outs gives you so much equity that you really don't need many folds to make it profitable.

ATs, vs a very tight opening range and tight callers with 100BBs doesn't play that well IMO. If the opponents are loose, and you have a reasonable chance of outkicking them with a T, it's an easier call. How often will you lose $50 or even your stack in the flop comes T62 or A93 and the tight guy has it or someone else. It sounds nitty, but it's just one of those problem hands where you'll often be guessing for very large bets quickly, or hit your top pair and only win the current pot, b/c nobody else has the A.

seems fine

3 betting sucks balls w/o some kind of dynamic. I like our hand for value postflop.
